Colorful 450V / 750V Fire Alarm Cables , Heat Resistant Electrical
Cable
1. Application
Flexible cable for medium mechanical stresses. Permitted frequent
bending and twisting. Specially suitable for application in
household, kitchens and offices in dry and damp conditions, for
inst. washing-machines, dryers, refrigerators etc., as long as the
cable is adapted to essential specifications of the device. Also
suitable for cookers, i.e. hot devices, on condition that it does
not get in direct contact with hot parts of the device and is not
exposed to heat irradiation. Suitable for fixed installation in
furniture, partition walls, decorative linings and cavities in
prefabricated construction elements
